Typically, the cell will include more than three of these components. This includes grid driver, sensing, and protection functions.

Its core function is to switch motor power. Another scenario is moving into scale-up — electric transmission and servo drives.

Some power modules integrate functionality and intelligence far beyond these basic functions. But this is the power module, to say the least.

A power module is defined from three perspectives:
From an electrical point of view, Psus are busy when the physical integration is tight. They reduce the parasitic components in the interconnection of power semiconductor devices.

From the point of view of heat dissipation, the power module has a heat-conducting baseplate. This can be bolted to a radiator or cold plate to eliminate heat loss.

From a mechanical point of view, it provides powerful mechanical packaging for components.

In short, the power module is electric heating mechanical equipment. They are optimized for power converter operation.

Psus are usually used for higher power levels. Due to their robust mechanical construction, they can simplify the design of power converters.

In addition, they ensure normal operation from an electrical and thermal point of view. However, just follow the module datasheet specifications and guidelines.
